CHICKEN SCALDING MACHINE members IS are inclined upwardly and outwardly, as illustrated in Fig. 9 to receive the legs of chickens therebetween.

The rack i3 is mounted on the lower end of a rack actuating bar 28 by means of bolts 2|. It will be noted that the bolts 2| are mounted in slots 22 formed in the rack actuating bar 28, as illustrated in Fig. 3, to permit vertical adjustment of the rack along the rack actuating bar.

The rack actuating bar 28 is mounted for vertical reciprocable movement in bearings 23 provided on a suitable framework generally indicated at 24. The rack actuating bar 20 is normally held in its upper inoperative position to support the chickens above the tank 6, as illustrated in Fig. 1, by means of a helical torque spring 26 having its one end secured by means of a screw 21 to a shaft 28 and its other end secured by a screw 29 to a ratchet Wheel 3|. One end of the shaft 28 is journaled on a bearing 32 and the other end is journaled in the ratchet wheel 3|. A pulley 33 is secured to the shaft 28 to receive one end of a cable 34 Which has its other end secured to an eye bolt 36 provided on the lower end of the rack actuating bar 20. The ratchet wheel 3| is journaled in a bearing 31 and formed with ratchet teeth 3B for engagement by a pawl 39 pivotally mounted on a shoulder screw'4l. A handle 42 is welded to the outer end of the ratchet wheel 3| and is adapted to be'rotated in a lcounter-clockwise direction, as illustrated in Fig. 8, to place a predetermined torque load on the torque spring 26. It will be understood that the torque spring '26 acts through the shaft 28, pulley 32, and cable f':

34 to normally support the rack actuating bar 29 in its upper inoperative position when said rack actuating bar is supporting a plurality of chickens in the manner illustrated in Fig. 1.

A cam actuating arm 43 is pivotally mounted `l at 44 on the rack actuating bar 2|! and has a roller 46 journaled on its outer end for engagement with a cam 41 secured on a cam shaft 48. The cam shaft 48 is journaled in suitable bearings 49 provided on the frame 24 and is driven by means of a motor 5| through suitable pulleys 52 and 53 and a belt 54.

The cam actuating arm 43 is moved from its inoperative position, illustrated in Figs. 9 and 13, to its operative position, illustrated in Figs. 10 and 14, by means of a track member 56 when the rack actuating bar 28 is manually moved downwardly by pressure applied upon the handle 51. Fig. 10 clearly illustrates the manner in which the roller 46 moves along the track 56 during downward movement of the rack actuating bar 20, causing the cam actuating arm 43 to be thrown outwardly and upwardly into operative position as illustrated in Fig. 14. When the cam actuating arm 43 is disposed in operative position, a latch 58 is caused to be moved upwardly and outwardly'from its position, illustrated in Fig. 13, to its locking position, illustrated in Fig. I4. The latch 58 is pivotally connected to the cam actuating arm 43 at 59 and is provided with a locking shoulder 6| for engagement with a locking shoulder 62 provided on the rack actuating bar.

When the cam actuating arm 43 is disposed in its operative position, as illustrated in Fig. 14, rotation of the cam 41 acts through the cam actuating arm 43 to reciprocate the rack actuating bar 28 in a vertical direction, as illustrated in Fig. 10. It will be noted that the cam 41 acts to'mcve the rack actuating bar 26 downwardly,

while the torque spring 26 acts to yieldably resist downward movement of the rack actuating bar and to urge the latter upwardly to maintain the roller 46 in constant engagement with the cam 41. During reciprocative movement of the rack actuating bar 20, it will be noted that the chickens will be submerged within the scalding water contained within the tank 6, and that upward vertical movement of the rack actuating bar causes the chicken feathers to are outwardly away from the body of the chicken to permit the scalding water to contact the skin of a chicken adjacent the base of the feathers. By employing this-method of scalding chickens it has been learned that the chicken feathers become loosened within a relatively short time and that the chickens may be removed from the tank of scalding water before the skin of the chicken becomes discolored, or cooked.

The duration of thev chicken scalding operation is controlled by means of a timing apparatus which may be set to a predetermined time for the chicken scalding operation, and which acts to automatically permit the return of the rack actuating bar 20 to its upper inoperative position, illustrated in Fig. 1, at the termination of the chicken scalding operation. The timing mechanism, illustrated in Figs. 1, 5 and 6A comprises a timing shaft 63 journaled in suitable bearings 64 and secured against axial movement by means of collars 66 secured to the shaft and engaging opposing faces of the bearings 64. A worm gear 61 is secured to the inner end of the timing shaft 63 for engagement by a worm 68 secured to the cam shaft 48. A tooth clutch member 69 is secured to the outer end of theV timing shaft 63 for operative engagement with teeth 1| provided on a timing wheel 12 when the rack actuating bar 28 is moved downwardly to its operative position. The timing wheel 12 is journaled for rotational and axial movement on the timing shaft 63 and is normally held in its rearward inoperative position and out of engagement with the clutch member 69 by means of a compression spring 13. The timing wheel 12 is also normally maintained in its position, illustrated in Figs. 5 and 6, by means of a tension spring 14 having its one end secured to the frame 24 at 16 and its other end secured to a stop arm 11. The timing wheel 12 is normally disposed in the position illustrated in Fig. 6 in which the stop arm 11 is in abutting engagement against a stop pin 18 mounted on the frame 24.

When the rack actuating bar 20 is moved L downwardly to its operative position, a cam surface 19, formed on the bar 20, acts to move the free end of a clutch arm 8| in a forward direction. The clutch arm 8| is pivotally mounted on the frame 24 by means of a bolt 82 and is provided with an aperture to receive the timing shaft I|53. It will thus be noted that forward pivotal movement of the clutch arm 8| causes forward movement of the timing wheel 12 and engagement of the clutch teeth 1| with the clutch teeth provided on the clutch member 69.

During reciprocative movement of the rack actuating bar 2U, the cam surface 19 and clutch arm 8| act to maintain clutch teeth 1| in clutching engagement with the clutch member 69, thereby causing the timing wheel 12 to rotate in a counter-clockwise direction, as indicated by the arrow 56.

In order to terminate the reciprocative movement of the rack actuating bar 28 after a predetermined interval of time, a plurality of apertures mangues l lt vare `irsrovided in 'the 'irene .nf `thetiming iwheel .'2 to receive a timerlpinil. lhetimerzpin 84 is formed to :project uzesrwmtdly `throughe acsel-ected aperture al ifor iengagementmith -an-in'fiset -.phrti'on "186 formed :on: a 7:latch .releaseastop iarm llhe .arm @81 is licurnaled'iiorrraxialpmovement suitable bearngs B8-388, thesanm sel Vbeingmovable inane-direction responsive@ engagement by the 'timer pin 1.84 :andfarrovable 2in `:an .opposite idirection Thy means of a oompression spring `ist interposed between a' bearing i8! andavcollar S! necurerlto the arm $11.

In the `operation of the Amachine thus shown and described, the rack actuating .'bafr :is Lina-.nually moved from its inopelativeposition to its lower operative position, las illustrated in Figs. 9 and l0, respectively. Whenthe rack actuating bar 2l fis in y'its lower position, `the cam `actuated arm is held in operative engagemcntrrwithfthe 411, thereby providing a relatively shortstroke and neciprocative movement-of `'the racklactuat- `bar 3i?. After la ,predetermined interval pf time, fthe .-timing pin 84 4prox/'ideal on the timer 7plate l2 moves into .engagementlwth litre/,latch release stop arm 8l to cause the latter to be positioned in the line of travel of one end of the latch release lever 92. The latch release lever 92 then acts to release the latch 58 to permit the cam actuated arm 43 to return from its operative position, illustrated in Fig. 14, to its inoperative position, illustrated in Fig. 13. When the cam actuating arm 43 is returned to its inoperative position, the torque spring 26 acts to raise the rack actuating bar to its upper inoperative position.

While this invention has been shown in but one form, it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit and scope of the claimed invention.

I claim as my invention:
